Thermal insulation for a sustainable rehabilitation of traditional buildings

Experiences and testing made in the course of 15 years at the DJCAAR- Dipartimento di l ngegneria Civile. Ambientale e Architettura at the University of Cagliari, highlighted that the major interventions for the conservation and rehabilitation of traditional buildings are geoerally to be made oo openiogs aod roofs. Walls are, in fact, almost always io a pretty good condition, as are the horizontal limber frames between floors. Some recent researches o!Tered the possibility to experimeot new solutions for roof and wall insulalioo. Starting from lhe need to put together natural and very performiog materials, and lhe oeed to limit the traosportation of building elements for economic aod ecological reasons. some tests were made oo new paneis made with locally produced libers, waste product from olher artisanal production, and clay. Paneis made witb clay aod straw, loofal1 or hemp wood have been manufactured and tested bolh in restoration siles aod io lhe climatic chamber. The results obtained are very promising
